A study by Transparency Rwanda involving large scale surveys of Rwandan society and the prevalence of Bribery - the first of its kind by the NGO - showed a very low incidence of bribery. More than 80% of those surveyed had never come across corruption, and the incidence of bribery was put at 3.9%. However, of more concern was the fact that, whilst most Rwandans had never come across corruption, 56% of those who had done so had failed to report it. The police were identified as the largest recipient of bribes paid, at over 52% of reported bribes. The range of bribes identified through the surveys ranged from RwF 200 to RwF 600,000, averaging RwF 27,647. Transparency Rwanda was established in 2004 and has taken a leading role in the fight against corruption in Rwanda.
